so sorry - I meant to post this in the building forum! oops :)

If you only want them to be decorative, they are very cheap and easy to build. If you can build a picture frame, you can build these windows. You are looking at maybe $40 of wood/trim and $20 of glass.

Just seconding what bill said. We put one over an interior door, so it was only the width of a regular door, not as wide as the one that's in your picture. You get the glass from a glass company ( they cut it to size), and the rest is just carpentry work.

Just don't think I can make it look right with my 8' ceilings (but if someone wants to tell me otherwise, please do!).

Anyway, someone on here in the last 6 mo. (ok, needle in a haystack) added some in their kitchen reno and they were sooo great. I didn't clip the post though.

Actually, I should've searched first. It was tnhillbillytoo (linked below) and they are so nice!

Here is a link that might be useful: tnhillbillytoo's added transoms (pics)

I added them in 3 places in our kitchen remodel. I got salvaged stained glass and 2 leaded glass windows...very inexpensive from a salvage yard and my GC opened the area above the doorways and framed them in ...voila. Transoms. Here are pics to give you an idea. I like the look of the old windows but as was pointed out you could use just glass and make windows. Hope this helps...

between the kitchen proper and the area where the Frigidaire Twins are located...added a skylight too so this brings the light into our interior kitchen:

between kitchen and DR:

over doorway to foyer of Master bedroom...matches the leaded window in the same area with fridges...

here you can see the 2 windows and how they relate to the area:

I love that transom. I'm putting a similar one between my foyer and great room. My builder is very excited about it, especially since he's charging me about $1000 for it. I should have questioned why it was so much, but I didn't. It is a wide transom on a load-bearing wall, so maybe that has something to do with it. Who knows.

BTW, I don't think anyone around here would care that you posted to the wrong forum. They answer anything here!

I think a big part of the expense of Andersen-type windows is for their insulating value, their preventing air and water infiltration, and their rugged exterior finish. You don't need any of these for an interior transom. I agree with the others here who say frame it out and simply install a custom piece of glass in the opening.

Any good glass shop should be able to sell you the spacers to put around the edge of the glass, and the double-sided foam tape to make installing the glass a breeze.

I was able to DIY install the lower left square window in the following picture so that it matched the other five windows.

We have 9ft ceilings and added transoms several years ago. I ordered them to fit our existing door openings and they ranged in price from about $100 for a 30" to about $300 for a 5 ft opening. They were all 12" tall.

sorry for the blurry pic...

This is Jay Olson-Goude's home - exactly what I'd love for our new build. He says he has 9' ceilings and only the transoms going into the bedrooms & baths have glass.
